Mehhhh.... I dunno. The reason this might work at all is because the active ingredient in Listerine is eucalyptol, derived from eucalyptus oil, and it is well known that Oil of Lemon Eucalyptus is a very good organic repellent. But the concentrations in Listerine are vanishingly small, well under 1/10 of 1%, while effective repellents contain 40% to 50% essential oil.
It seems that the likelihood of listerine just sprayed around on surfaces having much effect is pretty small, but if you try it I'd be really interested to hear the results. A good experiment would be to mark off 3 1-meter squares in an area where you usually get critters living and spray the Listerine in one, nothing in another and OLE in a third, then count the populations over time.
